Strangely , the Xperia Z1 , the Z1 Compact and the Z Ultra are excluded in this list ,Although this can change later on , the Xperia Z1 series is quite capable in running Android 6.0 as all three devices have Snapdragon 800 Processors and 2GB Ram .

The Xperia Z series however has probably hit its end of life as the Tablet Z , Xperia Z , Xperia ZR and Xperia ZL has Snapdragon S4 processors which are no longer in service , the last updates the Xperia Z series received was Android 5.1.1 and this might probably be its last . Hopefully the Z1 will see better days .
